-verbose
causes
cascade
to tell the user exactly what it is doing. The
verbose
flag is propagated to
cheops(1)
which also runs in
verbose
mode.
-growth_protection
retrys
causes the system to retry an
sbrk(2)
call up to
retrys
times. This option permits the program to wait until the core that it requires
is available rather than simply exiting if
sbrk(2)
fails.
-help
invokes the on-line context help system for this application. This
"man" page is displayed. The process then exits.
-argf
argument_file
tells the filter to take its command line arguments from the specified
argument_file.
The data format of the argument file is:
# ... optional comment line ...
-argflag [1]
argument_parameter [1,1]
argument_parameter [1,2]
argument_parameter [1,n]
# ... optional comment line ...
-argflag [2]
argument_parameter [1,1]
argument_parameter [1,2]
argument_parameter [1,n]
-nice
cardinal
determimes the
niceness
at which the filter is scheduled. In keeping with all UNIX user processes, nice
must be a cardinal between 0 and 20. The default niceness for
cascade
is 19.
-usage
displays program shortform usage.
-version
displays program version number.
-slots
displays
pups(3)
libraries dependencies for application in short format giving version, source language,
programmer and copyright.
-sloinfot
displays
pups(3)
libraries dependencies for application in long format giving version, source language,
programmer and copyright.
-image_names
ref image name,
nref image name
specifies the (stereo) images to be used for
cascade(1)
autoseeding.
-tcf
PDL script file name
identifies the
scriptfile
which is to be used by
cheops(1)
which is called. Details of the
cheops(1)
pyramid discription language is given in the
cheops(1)
man
page.
In addition to passing the tcf script to cheops,
cascade
uses the
apex
statement in the tcf file to estimate the grid on which seedpoint estimation
is performed.
-matcher
ACM stereo matcher
passes the name of the ACM stereo matcher to the
cheops(1)
harness.
-blunderer
blunderer
passes the name of intertier blunder detector to the
cheops(1)
harness.
-reducer
image reducers
passes the name of the image reducer to the
cheops(1)
harness.
-trial_seeds
seeds
is used to specify the number of seedpoints in each trial batch produced by
cascade(1).
-required_seeds
seeds
is used to specify the minimum number of seedpoints when
cascade(1)
is operating as a brute force autoseeder.
-max_iter
is used to specify the iteration limit when operating as a brute force
autoseeder.
-grid
rows
cols
is used to specify a seeding grid of
rows
x
cols
which is used to define the position of trial seedpoints in the reference
image. This option increases the number of seedpoints which are produced when
cascade(1)
is operating in
brute
force
mode.
-offset_scaling_factor
scale_factor
tells
cascade(1)
to scale stereo offsets (input via the
-offset
or
-mean_offset
flags by the factor
scale_factor.
This option is normally generated automatically when
itg(1)
generates an autoseeder pipeline.
-offset
sample
line
is used to specify the offsets between the reference and non-reference images.
These offsets used when generating trial seedpoints for stereo imagery in
which features are
grossly
shifted between the reference and non-reference images.
-mean_offset
uses the seedpoint (or camera model orientation file) to compute the offset between
the reference and non-reference images. These offsets used when generating trial seedpoints
for stereo imagery in which features are
grossly
shifted between the reference and non-reference images. This option and the previous option
are mutually exclusive - only one of them may be specified.
